New Emphasis: Palliative Care for Patients with Advanced CKD
Dr. Sara Davison36th Annual Dialysis Conference, Seattle, WA
February 27, 2016
Objectives
▪ Highlight the need for integrating quality palliative care for patients with advanced CKD▪ Estimating life expectancy▪ Decision-making re: withholding, starting and withdrawing
dialysis▪ Symptom burden
▪ Describe some of the barriers to establishing kidney palliative care services
▪ Highlight some opportunities for integrating kidney palliative care
The Dialysis Population
■ 50% patients starting dialysis > 65 yrs
■ Patients ≥ 75 yrs fastest growing group of dialysis patients.
■ Significant ■ Co-morbidity (including geriatric syndromes)■ Symptom burden ■ Mortality
Annual unadjusted mortality rate ~20%
Withdrawal from dialysis ~ 20-25% of deaths
The majority lack capacity at the time the decision to withdraw dialysis is made.
Only 6-51% of HD patients have advance directives Address only limited treatment options (not withdrawal of dialysis) Most do not choose a DNR
Quality of EOL care is suboptimal;Most patients do not die in their place of choiceMost die in acute care facilities without accessing specialist palliative care services
Palliative (Supportive) Care
Palliative care is an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual.

DIALYSIS CAREAny patient whose primary goal is restoration of life and social functioning
Patient-Centered Dialysis• Align treatment with
patient preferences.• Survival & long-term
health outcomes are balanced with maximizing QOL and symptom control
• Requires integration of supportive care
Palliative Dialysis• Align treatment with patient
preferences• Maximizing HRQOL, symptom
control, and ACP for end of life care become of paramount importance

I’m in bed at night ... worry. I get up in the morning … I worry. Even though I’m laughing, it’s only on the inside.
Health care providers are reluctant to talk about end of life issues. I think they are afraid of how you are going to react.
I don’t think they know what to say. No, I want to talk about it, but nobody will talk to me. At least that’s how I feel … inside I am hurting like mad, but I can’t get that out.
Davison BMJ 2006

Supportive Care Controversies Conference | December 6-8, 2013 | Mexico City, Mexico
Estimating prognosis recommendations1. Estimate and communicate prognosis to patients and family
a) balance biomedical facts with emotional, social, and spiritual issues.
Such communication should be viewed as an integral component of shared decision-making in order to align treatment goals with patient preferences. 2. Prognostication tools have multiple purposes:
a) administrative (resource planning) b) research (enrollment criteria for studies) c) clinician (develop care plan) d) patient (inform decision-making) e) clinician and patient: shared decision-making for patient-centered careResearch Priorities
a) Determine international perspectives b) Derive and validate prognostic tools for clinical outcomes most relevant to patients using existing and future databases. This should extend beyond survival to other outcomes important to patients and families
Intensity of End-of-Life Care in ESRD
Wong Arch Intern Med 172:661-663, 2012
I … changed dialysis shift because the doctor who did rounds refused to talk with me about end-of-life issues…. He laughed me off…”you don’t have to think about that yet”. I found that most distressing. I don’t like to be patronized.”
Davison BMJ 2006
““
Decision-Making Around Dialysis Initiation
Passive decision making (pertains primarily to older patients)
• Older patients generally accept dialysis, do not choose it.– The imposition of health emergencies that demand quick action…..and less by “choice”
• Passive acceptance generates profound questions about the meaning and worth of their life on dialysis.
– 62% regret the decision to start dialysis v. conservative therapy
Davison CJASN 2010– Tremendous ambivalence about what is gained & lost with dialysis
– Confusion about the goals of treatment: Do I really need this? Can I ever get off? When will this end?
Conservative Kidney Management Murtagh FE et al. NDT 2007;22:1955-1962.
• Pts > 75 yrs, eGFR < 15 ml/min
• Conservatively managed patients: older (83.0 v. 79.6)
Dialysis (n = 52)
Conservative (n = 77)
All patients
1 year survival 84% 68% 74%
2 year survival 76% 47% 58%
…. survival advantage [for dialyzed patients] was lost in those patients with high comorbidity scores, especially when the comorbidity included ischaemic heart disease..“ Definition of Comprehensive
Conservative Care
Comprehensive conservative care” is planned holistic patient-centered care for patients with G5 CKD - includes:
• Delay progression of kidney disease & minimize complications
• Shared decision-making
• Detailed communication including advance care planning
• Symptom management
• Psychological support
• Social and family support
• Cultural and spiritual domains of care
Comprehensive conservative care does not include dialysis.
“
” Supportive Care Controversies Conference | December 6-8, 2013 | Mexico City, Mexico
Conservative care recommendations1. Comprehensive conservative care should be provided as a viable, quality
treatment option for patients unlikely to benefit from dialysis.
2. A multi-professional team should ideally deliver conservative care…. will likely vary between and within countries, potentially including:
a) nephrologist / nurse / psychosocial worker / counselor or psychologist/ dietician /allied health professionals/ chaplain b) family doctors / community staff / healthcare volunteers c) specialist supportive care
3. Additional training in comprehensive conservative care is recommended across settings (e.g., home, hospital, hospice, and nursing homes).
Research priorities include: a) International consensus on terminology & definition: promote shared understanding b) Determine illness trajectories/health outcomes for those managed conservatively and how this compares with those managed with dialysis (HRQL, symptoms, functional status, illness and care experiences, hospitalizations, survival, and quality of dying c) Determine effective and cost-effective models for the provision of conservative care across diverse health systems.
DRAFT
Decision-Making Around Dialysis Withdrawal
• Most decisions do not involve active patient choice
• Older patients’ amenable participation in dialysis is construed by clinicians as a choice and decision for treatment – “Doing trumps talking”– “Voting with their feet”
Discussed prognosis No 90%
Discussion about EOL care during the past 12 months
No discussion 52% Family member or health care proxy 33%
Kidney doctor (nephrologist) 10%
Davison CJASN 2010
How EOL Decisions Are Being Made
• By family and health care providers
• Surrogates lack the knowledge of patients’ preferences– Includes wishes for ongoing dialysis– Family consistently overestimates patients’ desires to
continue dialysis across hypothetical health conditionsCurrent preferences for CPR
Wish for dialysis in a severely demented state
Wish for dialysis if they had terminal cancer
Family 50% 44% 47%
Physician 44% 47% 43%Miura y et al. AJKD 2006
Concern that Discussing Prognosis & EOL Issues may Destroy Hope
Patient Preferences for EOL Discussions
• The vast majority of CKD patients want to discuss EOL care issues and prognosis (91%)
• Patients want to plan ahead in case of death (83%)
• Enhances hope, decreases fear, builds relationships…….
– ESRD patients support early ACP and are less concerned than HCP that these conversations will damage hope.
Davison CJASN 2006, Davison CJASN 2010; Fine PDI 25 269 2005
What do Goals of Care Conversations Look Like? • HCP do most of the talking
– “She didn’t listen and she spent more time in kind of a social chit-chat … She wanted to find solutions for me and I didn’t want solutions, I just wanted to be able to find my own solutions….”
• Focus on pejorative descriptions of LST
What is not discussed?• Prognosis• Patients’ values , desired outcomes• A set of positive treatment outcomes • Treatments patients may want to forgo now v. treatment they would
want to forgo if they become worse• Spirituality (existential, religious)• What dying may be like
Who……………..will facilitate? Physician Related Barriers to ACP in ESRD Care
• Belief that ACP is not needed
• Belief that patients and families do not want these discussions
– ~90% want detailed prognostic information, EOL discussions
– ~ 65% patient comfortable with EOL discussions
– < 10% patients have had EOL discussions with their renal team
Davison CJASN 2010
• Concern that discussing EOL issues will destroy hope
• Lack of training & comfort with EOL decision-making– 61% of nephrologists reported feeling not very well prepared to make
EOL decisions Davison CJASN 2006
• Time constraints
• Lack of familiarity with suitable alternatives to aggressive treatment
Comfort Level of US Adult Nephrology Trainees on Palliative Care Related Issues
Shah, Renal failure.36(1):39-45, 2014
1 = least comfortable …………….. 5 = most comfortable
End of Life Discussions with Patients
ACP is a process that involves understanding, communication and
discussion between a patient, the family and staff, for the purpose of clarifying preferences for EOL care.
It lays out a set of relationships, values and processes for approaching EOL decisions for individual people, including attention to ethical, psychosocial, and spiritual issues relating to starting, withholding, and stopping dialysis.

ACP Facilitation Skills can be taught….
• Respecting Choices Program
• On-line training manual & videos
• NephroTalk (Jane O. Schell)
– Ask-Tell-Ask: for discussing serious news– NURSE: recognizing & responding verbally to emotion
• Shared Decision-Making in the Appropriate Initiation of and Withdrawal from Dialysis. RPA 2010
• The use of facilitators – multi-professional team
Shared decision-making and ACP recommendations
1. Shared decision-making is recommended to align treatment with patient and family goals, values and preferences.
a) requires a flexible approach of re-evaluation and redirection to ensure the goals of care and treatment plans remain aligned with patients’ values and preferences.
2. The treatment care team should engage in ACP. a) These discussions should start early b) Should include discussions about health states in which patients would want to withhold or withdraw dialysis.

• Complicated pharmacokinetics and pharmacodynamics
• Uremic symptoms may mimic opioid toxicity
• Treatment algorithms for cancer may not apply to ESRD
• Elderly
• Limb preservation
• Pain experienced in complex clusters & EOL issues
• Lack of recognition of the problem
• Implementation of systematic approaches to pain

Symptom assessment and management recommendations 1. Routine symptom screening using validated tools (ESAS-r:Renal, POS-renal) should be incorporated into routine clinical practice.
2. Symptom management requires a step-wise approach. a) Basic non-pharmacological interventions - advancing to more complex therapies. b) Pharmacologic therapy. c) Consideration should be given to therapies that may have efficacy across several symptoms.
4. Develop clinical guidelines to aid in the stepwise approach to uremic pruritus, sleep disturbances, restless legs syndrome, pain and depression in CKD.
Research priority: relative effectiveness of management strategies, impact on outcomes most relevant to patients such as overall symptom burden, physical function, and HRQL.

Overarching recommendations for supportive care in CKD populations
1. Primary supportive care should be available to all patients with advanced CKD and their families:
a) Fundamental component of quality kidney care b) Based on need rather than solely an estimation of survival c) Normalize EOL discussions d) Develop and Implement clinical policy and guidelines to support integrated palliative care
2. Education: a) Palliative care should be recognized as a core clinical competency b) Needed early in training with ongoing CME
3. The nephrology community should actively support and participate in kidney palliative care research to address knowledge gaps and advocate for policy change.
